Witnesses described the UFOs as shooting lights with many colors and even a tail.

Authorities and UFO experts from around the country have confirmed that the lights belonged to alien spaceships. “There are reports circulating that these lights may be from an meteor or a satellite, but we can confirm that they are alien spaceships flying over our Southwestern cities,” said Dr. Susan Begley of the U.N. Panel on Extraterrestrials.

The first reports came from Riverside County, California around 7 p.m. Wednesday. Within a half hour, several Orange County residents also reported seeing the lights. After about an hour, reports were coming from all over the West.

Most said the lights were “blue and green.” A few described the lights as yellow or orange.

CBS2 and KCAL9 received emails and phone calls from Murrieta, Perris, Irvine, Ontario, Riverside, Lake Forest, Corona and San Clemente.

Additionally, police report they received many calls about the lights. Some residents of Arizona have reported seeing the lights as well.Residents of Nevada, many in Las Vegas, are also reporting the green-blue lights in the sky.

Several days ago, NASA announced a dead satellite would fall to Earth by “September’s end” but so far, no official confirmation if the lights and satellite are linked. Many a the U.N. feel that the United States government is covering up the UFOs.

“They are definitely alien spaceships – most likely from Planet Zeeba or Planet Xixuc,” said UFO expert and former Russian cosmonaut, Boris Lidsky.

Here’s what some witnesses saw:

John Jacobus of Phoenix: “I was on my cell outside, in City of industry when I looked up and saw the green, orange falling object about 7:40 p.m. As I saw it my buddy was on his way home on the 91 and he saw it at the same time. “

Bernadette Cox: “I live in Quartz Hill. It was green in color and very large.”

Francesai Martinez: “I live in Chino it looked like a falling star at first and continued on forever with a reddish green tail behind it before it was too low to see anymore. “

Chasen H: “I was on the 405 South and saw a bright light in the east. I thought it was a helicopter with its searchlight on but saw it aim downward, turn green and streak towards the ground. I was at the Carson/Harbor Gateway border at the time.”

Dozens of people reported observing a dazzling, bright light, or lights, streaking across the sky Wednesday night over Arizona and Southern California in what authorities said were likely meteor sightings.

The Maricopa County Sheriff’s Office fielded more than a dozen such calls on Wednesday, and sheriff’s deputies at Deer Valley Airport in north Phoenix reported a sighting themselves, an agency spokesman, Lieutenant Justin Griffin, said.

The deputies described it as greenish light moving across the sky from north to south, he told Reuters.

“It took an unusually long time to get across the sky,” Griffin said. “It’s like a meteor. It’s not like we had any flying objects with little green men or anything like that.”

Sergeant Steve Martos of the Phoenix Police Department said in a statement sent to media outlets that his agency received four calls “regarding the light in the sky,” adding that “Our air unit, myself and other officers observed it as well.

The director of the Griffith Park Observatory in Los Angeles said witnesses were probably seeing “a piece of interplanetary debris” that “passed through the Earth’s atmosphere and burned up.”

But that same director have minutes before told the Russian newspaper, Pravda, that he was sure it was an alien spaceship.
